[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage suction truck for sucking and transporting garbage stored in a garbage storage container, for example.

[0002]

2. Description of the Related Art Conventionally, this kind of garbage suction vehicle is equipped with a suction device and a refuse storage tank for storing refuse sucked by the suction device, and is connected to an inlet of the refuse storage tank by suction by the suction device. The garbage was stored in the garbage storage tank from the provided garbage suction pipe through the inlet.

[0003] A discharge plate is slidably provided back and forth in the dust storage tank, and when the dust in the dust storage tank is full or a certain amount of dust is accumulated, a dust suction operation is temporarily performed. After stopping, the dust in the dust storage tank was compressed by sliding the discharge plate back and forth. Further, when discharging dust, the discharge plate is slid to the rear of the dust storage tank to discharge the dust from the rear end of the dust storage tank.

[0004]

However, in the above conventional apparatus, when compressing dust, the dust suction operation is first stopped, and after the compression is completed, the suction operation is started again. The reason is that during the dust suction operation,
When the discharge plate is slid rearward to compress dust, when the discharge plate reaches behind the inlet, the dust sucked from the inlet through the suction pipe is stored in front of the discharge plate. For this reason, the dust cannot be compressed by sliding the discharge plate backward while continuing the dust suction.

Therefore, in the conventional apparatus in which the dust suction operation is stopped when compressing the dust, the suction operation takes a long time corresponding to the stop time, and the dust is compressed if a certain amount of dust accumulates. There has been a problem that the operation of stopping and restarting the suction is repeated many times, and the operation of the operator becomes complicated.

[0006]

Means for Solving the Problems The garbage suction truck of the present invention is:
A dust storage tank mounted on a vehicle frame and having a door at the rear, a suction pipe connected to the dust storage tank, a suction device for reducing the pressure of the dust storage tank, and two upper and lower stages in the dust storage tank. An upper discharge plate and a lower dust discharge / combination lower discharge plate that are separately provided and can move back and forth independently of each other. The width of the lower dust discharge / combination lower discharge plate is provided at the front upper end of the lower dust discharge / combination discharge plate. A horizontal member extending in the direction and a predetermined length forward is slidably provided at the lower end of the upper discharge plate.

[0007]

[Function] By dividing the discharge plate into an upper discharge plate and a lower dust discharge / combination lower discharge plate in two upper and lower stages, the upper discharge plate and the lower dust discharge / combination discharge plate can be independently moved back and forth. By moving the lower discharge plate only forward and backward without moving the upper discharge plate back and forth, the dust in the dust storage tank is compressed while continuing the dust suction operation.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

First, before describing the dust suction vehicle of the present invention, the configuration of the entire dust suction transport system for sucking and transporting dust by the dust suction vehicle will be described.

FIG. 1 is a block diagram schematically showing a dust suction / transport system.

In FIG. 1, reference numeral 1 denotes a garbage storage container installed on a basement floor of an apartment house or the like. This garbage storage container 1
The lower end of the chute 2 is connected to the upper part of
One end of a connection pipe 3 is connected to a lower portion of the trash storage container 1. The other end of the connection pipe 3 is extended to a docking station 5 installed at an appropriate place on the ground, and is detachably attached to a suction pipe 30 provided in a garbage storage tank 20 of a garbage suction car C by an appropriate coupling. It has been done.

Reference numeral V1 in the drawing denotes an on-off valve provided at the lower end of the chute 2, V2 denotes an on-off valve provided at one end of the connecting pipe 3, and V3 introduces outside air into the dust container 1. This is an on-off valve provided in the introduction pipe 4.

As shown in FIG. 2, the dust suction truck C has a suction device 10 and a dust storage tank 20 for storing dust sucked by the suction device 10.

The suction device 10 has a suction passage 11 having one end connected to the dust container tank 20 and the other end open to the atmosphere.
And a water task rubber 12 provided in the suction passage 11.
And a blower 13 provided in the suction passage 11 closer to the atmosphere than the water scrubber 12, and a muffler 15 provided in the suction passage 11 closer to the atmosphere than the blower 13.

As shown in FIG. 3, one end of the suction passage 11 is communicated with the dust storage tank 20 through suction ports 24, 25, and 26 formed on the front and front surfaces of the dust storage tank 20, respectively. ing. Therefore, by operating the blower 13, the pressure of the dust storage tank 20 and the dust storage container 1 is reduced.

In FIG. 3, reference numeral 27 denotes a filter provided at the suction port 26, and reference numeral 28 denotes a cover.

The garbage storage tank 20 is formed by an opening / closing door 21 whose rear end wall opens rearward with the upper end edge as a center, and a discharge plate 22 slidably disposed in the garbage storage tank 20 in the front-rear direction. The garbage stored in the garbage storage tank 20 is configured to be dumped to the rear of the vehicle.

The discharge plate 22 is composed of an upper discharge plate 22a and a lower dust discharge / compression plate 22b which are divided into upper and lower two stages. The upper discharge plate 22a and the lower discharge plate 22b are also provided. Telescopic cylinder 2
3a and 23b are provided so as to be slidable in the front-rear direction. A horizontal member 24 is provided at a front portion of the upper end of the lower dust discharging / combining plate 22b in the width direction of the lower dust discharging / combining lower plate 22b and extends forward by a predetermined length. Numeral 24 is provided slidably at the lower end of the upper discharge plate 22a. Therefore, when only the dust compression / lower discharge plate 22b described later moves rearward, the horizontal member 24 prevents the dust from entering the front of the dust compression / lower discharge plate 22b.

The suction pipe 30 is connected to the dust storage tank 2.
A swivel pipe 31 connected to an inlet 29 formed at the top of the swivel pipe 3 and rotatably provided around a vertical axis;
1, a flexible tube 32 connected to the flexible tube 32 and capable of tilting up and down, and a telescopic tube 35 connected to the tilt tube 33 and capable of expanding and contracting in the horizontal direction. ,
A flexible tube 36 connected to the telescopic tube 35;
And a front end portion 37 connected to the end portion. Reference numeral 38 denotes a support member for supporting the distal end portion 37.

When a dust suction operation is performed by the dust suction vehicle C configured as described above, the dust suction vehicle C is brought to the docking station 5 and stopped, and then the swivel pipe 31 is turned to suck the dust. The entire pipe 30 is turned to the side of the vehicle, and the tilting pipe 33 is tilted,
The distal end 37 of the suction pipe 30 is connected to the docking station 5 by the expansion and contraction of the dust pipe, whereby the dust storage tank 20 and the dust storage container 1 are communicated via the connection pipe 3 and the suction pipe 30. Then, after closing the on-off valves V1 and V3 and opening the on-off valve V2, the blower 13 is operated to make the trash storage container 1, the connection pipe 3, the suction pipe 30, and the trash storage tank 20 into a negative pressure. By opening the valve V3 and introducing the outside air into the refuse storage container 1 from the introduction pipe 4, the refuse in the refuse storage container 1 is suction-transported to the trash storage tank 20.

Here, during the operation of sucking dust into the dust storage tank 20 by the dust suction truck C, the lower dust discharge / combination / lower discharge plate 22b in the dust storage tank 20 is moved by the telescopic cylinder 23b, for example, every predetermined time. The dust is reciprocated back and forth between the solid line position and the two-dot chain line position 22b 'in FIG. 2, and the dust in the dust storage tank 20 is compressed by sliding the dust compression / lower discharge plate 22b. I do. At this time, the upper discharge plate 22a does not slide back and forth, and the suction pipe 30 and the introduction port 29 are moved by the dust suction operation.
The refuse sucked through the refuse is stored in the refuse storage tank 20. That is, it is possible to compress the dust in the dust storage tank 20 while continuing the dust suction operation.

Further, the dust in the dust storage tank 20 can be efficiently compressed by sliding the dust compression / lower discharge plate 22b back and forth every time a predetermined time elapses to compress the dust.

To discharge the refuse in the refuse storage tank 20, the open / close door 21 is opened upward, and then the upper discharge plate 22a and the lower refuse discharge plate 22b are simultaneously moved rearward (ie, the refuse storage tank). The dust in the dust storage tank 20 is discharged by sliding (to the rear end of the dust storage container 20).

The garbage suction truck of the present invention is not limited to sucking garbage stored in the garbage storage container 1, but can also suck the garbage directly from the tip of the suction pipe 30, for example.

[0025]

As described above, according to the present invention, the upper and lower discharge plates and the lower discharge plate for both dust compression are arranged in the upper and lower parts.
The upper discharge plate and the lower dust discharge / combination lower discharge plate can be moved back and forth independently of each other, so that only the lower dust discharge / combination discharge plate can be moved back and forth without moving the upper discharge plate back and forth. By doing so, it is possible to compress the dust in the dust storage tank while continuing the dust suction operation, so that it is not necessary to stop the suction operation at the time of dust compression, and it is possible to shorten the suction work time,
The operation of the operator is easy and the dust can be efficiently compressed.
